NTU invents smart window that tints and powers itself

摘要

Scientists from Nanyang Technological University (NTU) in Singapore have developed a smart window, which can darken or brighten without the need for an external power source. This unique self-tinting window requires zero electricity to operate and is also a rechargeable battery. The window's stored energy can be used for other purposes, such as to light up low-powered electronics like a light emitting diode (LED).
